You: '
The Day of the Lord is the 1000 year Millennium.'
Nonsense; but more important, non-Scripture!
You: '
It certainly isn't one human day.'
That makes sense, and more important, is "according to the Scriptures ... the third day", That Day of Christ's Resurrection from the dead and therefore of ours as well it shall be at his coming again.
You: '
the Heavenly Places, where Christ ascended to and now sits at the right hand of God'
Now here's one to get your brains around. I am telling you God raised Christ and exalted Him "in the Heavenly Places, right inside the grave of Joseph hewn in rock on earth - right, "at the right hand of God", where, and "WHEN God raising Christ from the dead by the exceeding greatness of His Power exalted Him at his own Right Hand : HIS HEAVENLY MAJESTY"!
And Isaiah confirms,
15For thus saith
The High and Lofty One that inhabiteth eternity,
15Τάδε λέγει κύριος ὁ ὕψιστος ὁ ἐν ὑψηλοῖς κατοικῶν τὸν αἰῶνα,
whose Name is The Most Holy Place,
ἅγιος ἐν ἁγίοις ὄνομα αὐτῷ,
The Lord Most High and Holy being rested up again,
κύριος ὕψιστος ἐν ἁγίοις ἀναπαυόμενος
Paul also, Romans 1
3Concerning his Son (Jesus Christ our Lord)
(concerning Him) which was made |of the seed of David |according to the flesh
(concerning Him which was)
declared |the Son of God with power |according to the Spirit
(concerning)
HIS HOLINESS BY THE RESURRECTION FROM THE DEAD:
(concerning) Jesus Christ our Lord
By whom we have received grace ... for his name
You: '
Christ said in Matthew 23:39 that He wouldn't return until Israel accepted Him. Therefore, since there is no Israel today that could accept Christ, there is absolutely no possibility of His return, until this period is over, in about 2063 at the earliest.'
Speculation! In my Taal we say, 'spekskiet' - 'shoot with pig fat'.
